Title: Tissue separation cannula with dissection probe and method
Inventor: CHIN ALBERT K
IPC: A61B1/00
Filed: 1997-01-24
Abstract: A cannula (100) includes a tubular body (102) having a proximal end (104) and distal blunt end (106), at least one lumen (108) extending the length of the body (102), an endoscope (110) having a lighted, viewing end (112) disposed in the lumen (109) near the distal end (106) of the body (102), and a transparent, tissue separating tip (122) substantially covering the distal end of the body. The tissue separating tip (122) is slightly blunted to inhibit avulsion of tissue and lateral vessels along the dissected cavity formed thereby. Endoscopic viewing through the tip is enhanced by tapering the inner walls thereof to a cusp (120) adjacent the blunt tip in order to reduce visual distortion. Alternatively, a cannula includes a dissection probe (907) and endoscope (110) to facilitate viewing and the dissection of connective tissue and lateral vessels along the dissectible cavity.

Patent CA-2252825-A1 (CA)
Inventor: ACKER DAVID E
IPC: A61B5/08
Filed: 1998-02-25
Abstract: A probe such as an endoscope equipped with a biopsy needle is guided to a target in or adjacent to the respiratory system. The position of the probe is monitored. A representation of the probe is superimposed on a previously acquired image of the respiratory system and adjacent tissues. Artifacts caused by motion due to respiration are suppressed by monitoring the respiratory state of the patient, and acquiring the probe position when the respiratory state of the patient is equal to the respiratory state of the patient during image capture.
Patent CA-2253779-A1 (CA)
Title: Hydraulic control valve system with split pressure compensator
Inventor: PEDERSEN LEIF
IPC: F15B11/05
Filed: 1998-02-23
Abstract: An improved pressure-compensated hydraulic system for feeding hydraulic fluid to one or more hydraulic actuators (20). A remotely located, variable displacement pump (18) provides an output pressure equal to a control input pressure plus a constant margin. A pressure compensation system requires that a load-dependent pressure be provided to the pump input through a load sense circuit. An isolator (92) transmits the load-dependent pressure to the pump control input, while preventing fluid from leaving the load sense circuit and flowing to the remotely located pump (18). A valve section (13, 14, 15) which controls the fluid flow between the pump (18) and actuator (20) has a pressure compensating valve (48) with a piston (64) and a spool (60) controlling a pressure differential across a main control valve orifice (44) by moving within a bore (62) in response to a pressure differential between a pump supply pressure and the load sense pressure. The piston (64) and the spool (60) also separate to shut off fluid to the actuator (20) when the back pressure from the load exceeds the pump supply pressure.

Title: Process and device for reception with directional resolution
Inventor: FUHL JOSEF
IPC: H04Q7/36
Filed: 1997-05-20
Abstract: To adjust and adapt the directional diagram of a group antenna (antenna elements 1 to M) a decision feedback process is used in the first instance which subsequently is shut down for the detection of the subscriber data while the sum of the weighted signals of the individual antennae is directly passed on to a MLSE unit (maximum likelihood sequence estimator) (200). The decision feedback structure (100) can, for the purpose of continuous adaptation of the weighting factors (W11 to WMR) remain permanently switched on, while concurrently the MLSE unit (200) is detecting the subscriber data.

Patent CA-2260779-A1 (CA)
Title: Mobility-based and normalized capillary electrophoresis
Inventor: LIKUSKI ROBERT K
IPC: G01N27/447
Filed: 1998-05-14
Abstract: Identification and quantification of constituents of a sample is achieved by mobility-based electropherograms obtained from capillary electrophoresis, the mobilities being normalized by zero correction followed by division by the mobility of a selected marker. Zero correction is achieved either relative to a separate marker or by calculation based on the same marker. The resulting electropherograms are more recognizable since they more closely resemble the scanned separation patterns obtained with planar gels, and individual constituents of the sample are more easily and reliably identified since their positions in the electropherogram are substantially constant from one electropherogram to the next and hence reproducible to a high degree of accuracy.

Title: Method and apparatus for determining activation status of a receiving station of a radio communication system
Inventor: JOHANSSON CARL FREDRIK
IPC: H04L12/56
Filed: 1997-09-26
Abstract: Apparatus and method (110) for determining the activation status of a receiving station (14) of a communication system (10). A sending station (12) determines the activation status of the receiving station (14) to be active, possibly inactive, or inactive. When the receiving station (14) is only temporarily unable to receive signals transmitted thereto by the sending station (12), the sending station (12) is less likely to determine the receiving station to be inactive as the receiving station (14) is first determined to be possibly inactive.

Title: Projection lens and focus adjusting method for projection lens
Inventor: SUGANO YASUYUKI
IPC: H04N5/74
Filed: 1999-04-21
Abstract: To achieve a projection lens which has a wide angle view, a short projection distance and telecentricity and in which the projection can be performed with high contrast, various aberrations such as distortion aberration, etc. are reduced and the optical path is converted.     A first lens group having negative refractive power and second and third lens groups having positive refractive power are arranged from a longer conjugate side. Representing a back focus at a projection distance of infinite point by BF; the composite focus distance of the entire system by F; the central air spacing between said first lens group and said second lens group by GD1; the composite focus distance of said first lens group by Fl; the composite focus distance of said second lens group and said third lens group by F23; and the central air spacing between said second lens group and said third lens group by GD2, the following equation is satisfied: [2.8 < BF/F] [3.0 < GD1/F < 4.50][0.40 < -F1/F23 <0.48][0.40 < GD2/F23 <0.8].  At this time, the focus adjustment is carried out by moving the first lens group along the optical axis OA.

Patent CA-2272715-A1 (CA)
Inventor: DALTON MICHAEL
IPC: G06T15/08
Filed: 1997-11-17
Abstract: The present invention includes a method and apparatus for simulating, for example on a desktop computer, a specific view of a hologram. A preferred embodiment of this invention suitably enables, in medical imaging, the manipulation of intensity transformations (windowing and leveling), regions (cropping) and views (axial, coronal and lateral) and the display of the resulting simulations in substantially real time. In accordance with one aspect of the present invention, an approximation of substantially accurate pixel intensities is achieved by collapsing three-dimensional data onto a twodimensional view, without the need for constructing complex summations of fringe patterns, as is typically required when constructing a hologram. A power function is suitably applied to each voxel in the data set. The values for a particular x, y coordinate are then summed along the z axis, with the resultant sum value being stored in a sum buffer for all values of x and y. The maximal value of the sum buffer is determined, then the sum buffer values are normalized by this maximum value. Finally, an inverse power function is applied to the normalized sum, then the results are scaled over the range of values of the output buffer. Consequently, the operator is able to view, in substantially real time, simulations of a single view of a hologram created from the selected parameters.
